Key Parameters

Substitute Part Grouping Explanation

Substitution of the LHLP10NL101KB is determined by the following critical parameters:

Inductance Value: Both the main part and substitute must maintain 100 µH inductance to ensure circuit functionality.

Shielding Requirement: The shielded construction is mandatory for electromagnetic interference mitigation in the target application.

Core Material: Ferrite core construction is required for the specified frequency response and performance characteristics.

Mounting Configuration: Through-hole radial, vertical cylinder mounting ensures mechanical and electrical compatibility with existing PCB layouts.

Physical Dimensions: The 0.433" diameter (11.00mm) constraint accommodates board-level space requirements.

Current Handling Capability: The substitute must support the application's current demands without saturation or thermal degradation.

Compliance Standards: RoHS3 compliance is mandatory for regulatory adherence.

The Würth Elektronik 7447471101 satisfies these substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 7447471101 is a direct functional substitute for the obsolete LHLP10NL101KB. Both components share identical inductance values, shielded ferrite core construction, and through-hole radial mounting configuration with matching 11.00mm diameter specifications.

The 7447471101 provides superior electrical performance with a current rating of 1.6 A compared to the 900 mA rating of the original part, along with lower DC resistance of 190mOhm maximum versus 300mOhm maximum. The substitute operates across an extended temperature range of -40°C to 125°C, exceeding the original -25°C to 105°C specification.

Both components maintain ROHS3 compliance and are classified under identical HTSUS and ECCN codes. The 7447471101 is currently in active production status with confirmed inventory availability, ensuring long-term supply chain continuity.

The maximum seated height difference of 0.020" (0.50mm) between the two components is negligible for standard through-hole PCB applications and does not impact mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 7447471101 directly replace the Taiyo Yuden LHLP10NL101KB in existing designs?

A: Yes. Both components maintain identical 100 µH inductance values, shielded ferrite core construction, and through-hole radial mounting with 11.00mm diameter specifications. The physical and electrical compatibility is confirmed across all critical parameters.

Q: What is the significance of the inductance tolerance difference between ±10% and ±20%?

A: The LHLP10NL101KB specifies ±10% tolerance while the 7447471101 specifies ±20% tolerance. Circuit designs must accommodate the wider tolerance band of the substitute part. Applications requiring tighter inductance control should evaluate this parameter against specific circuit requirements.

Q: Does the lower DC resistance of the 7447471101 affect circuit operation?

A: The 7447471101 provides 190mOhm maximum DC resistance compared to 300mOhm maximum in the original part. Lower DC resistance reduces resistive losses and heat generation, representing an improvement in electrical performance. This change does not negatively impact circuit compatibility.

Q: Are there physical space constraints due to the height difference?

A: The 7447471101 has a maximum seated height of 0.453" (11.50mm) compared to 0.433" (11.00mm) for the LHLP10NL101KB. The 0.020" (0.50mm) difference is within standard PCB design tolerances and does not create mechanical interference in typical through-hole applications.

Q: What is the advantage of the extended operating temperature range?

A: The 7447471101 operates from -40°C to 125°C, compared to -25°C to 105°C for the original part. The extended range provides greater thermal margin and supports applications requiring operation in more extreme environmental conditions.

Q: How does the higher current rating of the 7447471101 benefit the application?

A: The 7447471101 is rated for 1.6 A continuous current with a saturation current of 1.4 A, compared to 900 mA for the LHLP10NL101KB. This higher rating provides additional design margin and allows the component to handle transient current spikes without saturation, improving circuit reliability.

Q: Are both components RoHS compliant?

A: Yes. Both the LHLP10NL101KB and 7447471101 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
